IMPROVEMENT IN TlRE-UPSETTERS.

S ecificati0uforming part of Letters Patent N 0. 178,082, dated Maly 30, 1876; application filed May 1, 1876.

Goshen, Orange county,state of New York,

have invented a neW and lmproved Tirebhrinker, of which the following is a specifica-- tion a side view of my improved tire-shrinker, part being broken away to show the construction. Fig. 2 is a top view of the same.

The ohject of this invention is to furnish an improved machine for shrinking tires and 0ther irons easily and qi1ickly, and which shall be Simple in construction, convenient in use, and inexpensive in manufacture.

The invention consists in the combination of the stationary plate, the sliding plate, the toothed blocks, the toothed eccentrics, the crank.arm,the rock-shaft, and the lever With each other, and with the bed or lraxne, as hercinafter fully described.

A represents the bed or'frarne of the machine, to one end of which is attached the end of a plate, B. .The plate B inclines upward, and projects inward, and its inner end rests upon, and is attached to, a stuc], b, attached to the middle part of the bed A. 0 is a plate, the inner end of which isnotched to receive, and tests and slides upon, the inner end of the plate B, and is kept from rising from said plate by fianges formed upon its side edges. The outer end of the sliding plate 0 is supported by, and pivoted to, a crank-arm, D,

In the accompaning dnawin, Figurel is formed upon the shaft E, which worksin bearings attached to the bed A. To the forward end ofche shaft B is attached the lever F, by which the machine is operated. To the rear side of the outer ends of the Stationary plate B and the sliding plate C, 01 t0 lugs formed upon said rear side, are attachedblocks G,

having ratchet -teeth formed upon the forward sides. To the forward side of the plates B C,onto lugs formed upon said forward sides,are pivoted the eccentrics H, which have teeth formed upon them, andar'e provided With lever-handles I.

With this construction the tire or other iron to be shrunk is heated, plaoed upon the plates B C, and clamped against the toothed blocks G by the eccentrics H I. Then, byoperating the lever E, the plate 0 and its toothed block and eccentric are forced forward, shrinking the iron.

Having thus described my invention, wlxat I claim as new, and desire to secu1re by Letters Patent, is

In combination with the clamping-jaws of a tire-upsetting machine, the stationary plate B, and the sliding plate 0, the latter lapping upon and acruss the former, and hinged at its opposite end, substantially as described.
